Abstract
A structure and method are provided for preventing or at least minimizing thermally-induced structural distortions, such as may occur when a steam turbine is cooling down. The steam turbine may include an inner housing and an outer housing. An intermediate space is formed between the inner housing and the outer housing, and sealing steam may be injected into the intermediate space to avoid the formation of temperature strata in the interspace and thus prevent the outer housing from bowing.
